Abstract
Objective. To identify associations of beta-adrenoreactivity with stage of chronic heart failure (CHF) in patient with previousmyocardial infarction (MI).Material and Methods. A total of 50 patients with CHF underwent an analysis of adrenoreactivity based on the changes in red blood cellosmoresistance in the presence of adrenergic blocker to determine the activity of the sympathoadrenal system a year after MI.Results. Higher levels of beta-adrenoreactivity (β-ARM) were characteristic of patients with CHF of higher gradations: 61.8(47.5;74.8) с.u. in patients with stage IIA CHF versus 48.7 (39;65.2) с.u. in patients with stage I CHF, p=0.037.Conclusion. These results may suggest the diagnostic value of the indicator of adrenoreactivity and its possible use as a newbiomarker for assessing the severity of CHF in patients with previous myocardial infarction.
